Solar Assistant Monitor for Growatt SPF Inverters | Raspberry Pi 4

This Raspberry Pi 4 unit comes pre-loaded with Solar Assistant software for real-time monitoring of Growatt SPF off grid inverters. It is a plug-and-play device with no subscription or renewal fees, and it includes the USB communication cable built for the Growatt SPF port.

Key features

• Processor, Raspberry Pi 4, 1.8GHz quad-core, 64-bit
• Memory, 2GB RAM with 8GB onboard eMMC
• Connectivity, WiFi 2.4GHz/5GHz and Ethernet 1Gbps, plus 4x USB ports
• Storage, Lexar 32GB MicroSD card preloaded with the monitoring software
• Power options, 230V mains to USB-C 5V/3A, or DC-DC 9-60V input to USB-C 5V/3A for direct battery power
• Enclosure, black aluminium case, fully assembled, with cooling pads fitted inside

Compatibility

Built for the Growatt SPF series complete kit. It also works with Pylontech lithium batteries (US2000C, US3000C, US5000C) using an additional cable, and with Victron Smart Shunt resistors (500mA and 1000mA) via a VE.Direct to USB cable.

Battery-powered monitoring

The DC-DC power supply lets the unit run straight from a 12V, 24V or 48V battery, so monitoring continues even if the inverter loses AC power or trips into fault mode.

Remote access

Once connected to WiFi or Ethernet, the system can be viewed remotely, showing live graphs of power, battery and system data without any programming needed. Multiple inverters running in parallel can be monitored by adding extra communication cables.
